    2. Click Cloud Connect Network on the left sidebar to enter the CCN management page.
    3. Click +New. The New CCN instance page appears.

      You can associate more instances after the CCN is created.

    5. Click OK.

    Step 2: Use Account B to Apply for the VPC Association.

    3. On the Associate with Instance tab, find the information about the VPC to be approved, and click Accept to add the VPC to the CCN.

    Step 4: Checking the Route Table

    2. Click Route Tables to view the route table of this CCN instance.
    3. Check if there is any invalid routing policy.

    Step 5: Setting Cross-region Bandwidth Cap (Optional)

    1. In the CCN list, click the ID of the desired CCN ID.

    2. Click Bandwidth Management. Click Change to change the speed limit mode.

      The default bandwidth cap is 1 Gbps. If you want to increase the bandwidth, submit a ticket.

      • Inter-region bandwidth limit
        Click Change Bandwidth to go to the Change Bandwidth page. Select Region A and Region B and enter the Bandwidth Cap. If you need to add more entries, click Add. Click OK to finish.
